车辆在各种道路条件下行驶,例如干、湿及冰雪覆盖路面,因此需要改善轮胎性能以适应各种道路条件。目前,传统的轮胎技术改善一个特性并不困难,但是一个特性的改变往往意味着另一个特性可能被牺牲掉。例如,无镶钉冬季轮胎在冰或雪面上有一种特殊性能,然而却很难同时提高在冰和雪? Vehicles travel on a variety of road conditions, such as dry, wet and snow-covered roads, and therefore need to improve tire performance to suit a variety of road conditions. At present, it is not difficult for traditional tire technology to improve one characteristic, but changing one characteristic often means that another characteristic may be sacrificed. For example, studless winter tires have a special property on ice or snow, but it is hard to improve both in ice and snow at the same time.
